Experimental Analysis of Tillage Tool Shovel Geometry on Soil Disruption by Speed and depth of operation

摘要

Tillage tool shovels with different geometry designed to perform a soil bed preparation by rotary or sweep action which performs a loosening and steering the soil .The Soil condition with its physical properties such as Soil Structure, texture, moisture, resistance, cone index like influencing parameters are creating a demand of different shapes of tillage tool geometry as the operational parameters needs to be optimized by studying a Soil Vs tillage tool interface. Furrow parameters such as furrow bottom, soil throw, soil disturbance in vicinity of tool in relation to speed and depth of operation are affected by tool parameters like shape, size. In this paper effect of tool shape and depth and speed of operation on soil disruption of shovels and sweeps for tractor drawn cultivator is discussed .The experiments were conducted in sandy loam soil using two commonly used shovels and sweeps at four forward speeds (0.97, 1.25, 1.53 and 1.81 m/s) and depths (0.04, 0.08, 0.12 and 0.16 m) at soil moisture content of about 10.5 per cent (db) under controlled soil bin conditions.
